National Museum of Australia curator Jennifer Wilson joined Claire Gorman in the 666 Drive studios to cast back the veil and have a good hard look at another treasure from our national collection in the weekly Treasure Trove segment.

This week it was all about the work of German inventor Carl Zeiss, who developed this folding photo-micrographic apparatus which enabled detailed photographs to be taken using the microscope like a lens in the 1920's.

Investigating tropical diseases like dengue fever, malaria and yaws were just a few of the research subjects that the photo-micrographic apparatus was used on at the Australian Institute of Tropical Medicine, the first medical research institute in Australia established in Townsville in northern Queensland in 1910.

The 'Spirit of Inquiry' exhibit featuring the photo-micrographic apparatus brings together stories from Townsville, Port Macquarie and Canberra and it is currently on display in the National Museum's Landmarks gallery.
